Answer:
x is 75° ........................
Answer:
x < 2.4
Step-by-step explanation:
5x < 12
x < 12/5
x < 2.4
On the number line, draw an arrow going towards left from 2.4, with an open circle at 2.4
Say she chooses topic A. She needs at least one book to arrive on time. The probability that no books arrive on time is 0.1 x 0.1 = 0.01 so the probability that at least one book arrives on time is 1 - 0.01 = 0.99.
Say she chooses topic B. She needs at least two books to arrive on time. The probability of no books arriving on time is 0.1 x 0.1 x 0.1 x 0.1 = 0.0001. The probability of exactly one book arriving on time is 4 x 0.1 x 0.1 x 0.1 x 0.9 = 0.0036 (binomial probability distribution formula - the 4 comes from 4C1). So the probability of her not getting enough books is 0.0001 + 0.0036 = 0.0037 and the probability she does get the books she needs on time is 1 - 0.0037 = 0.9963.
So she should choose topic B.
Hey!
Yes it is because there is a common difference the whole way. A specific number is added to each term.
8-3 is 5 so the answer is A!
Hope this helps!
